Question:
Ramya has a rectangular cardboard of length 55 cm and breadth 45 cm respectively. He wanted to cut the rectangular cardboard into smaller rectangles of 21 by 5 cm. How many pieces can he cut ? Find the dimensions of the left over cardboard.
Given:
Big rectangular cardboard = 55 cm by 45 cm
Smaller rectangular cardboard = 21 cm by 5 cm
To Find:
The number of cardboards he can cut
The remaining dimension of the cardboard
Solution:
If he wants to achieve the maximum number of smaller cardboards, he has to cut the 21 cm along the 45 cm length.
Number of cardboard he can cut length-wise:
Number of cardboards = 45 ÷ 21 = 2 remainder 3 cm
Number of cardboard he can cut breadth-wise:
Number of cardboards = 55 ÷ 5 = 11
Find the number of cardboards he got:
Number of cardboards he got = 2 x 11
Number of cardboards he got = 22
Find the remaining cardboard:
Remaining cardboard = 3 cm by 5 cm
Answer: He will get 22 smaller cardboards with the remaining 3 cm and 5 cm left.
Answer:
he will get 22 smaller cardboards with the remaining 3cm and 5cm left
